Sisal pads?...not sure if it's the same as the brush. The brushes are usually oval and often have a detachable long wooden handle on them...they sort of look like the brushes you would brush a horse with. The bristles are a bit finer than broom bristles and a light straw color. Hope that's what you got...
You can use it everyday...more than once if you want to. I know the brush is pretty stiff...especially when new...but your skin will get accustomed to it. Don't scrub your skin...just brush with long strokes...and you don't have to brush very hard to get good results. If your skin gets pink that's plenty! ; )
